1 And the LORD called unto Moses, and spake unto him out of the tabernacle of the congregation, saying, 2 Speak unto the children of Israel, and say unto them, If any man of you bring an offering unto the LORD, ye shall bring your offering of the cattle, even of the herd, and of the flock. 3 If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD. 4 And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him. 5 And he shall kill the bullock before the LORD: and the priests, Aaron's sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation. 6 And he shall flay the burnt offering, and cut it into his pieces. 7 And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire: 8 And the priests, Aaron's sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar: 9 But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the LORD. 10 And if his offering be of the flocks, namely, of the sheep, or of the goats, for a burnt sacrifice; he shall bring it a male without blemish. 11 And he shall kill it on the side of the altar northward before the LORD: and the priests, Aaron's sons, shall sprinkle his blood round about upon the altar. 12 And he shall cut it into his pieces, with his head and his fat: and the priest shall lay them in order on the wood that is on the fire which is upon the altar: 13 But he shall wash the inwards and the legs with water: and the priest shall bring it all, and burn it upon the altar: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto the LORD. 14 And if the burnt sacrifice for his offering to the LORD be of fowls, then he shall bring his offering of turtledoves, or of young pigeons. 15 And the priest shall bring it unto the altar, and wring off his head, and burn it on the altar; and the blood thereof shall be wrung out at the side of the altar: 16 And he shall pluck away his crop with his feathers, and cast it beside the altar on the east part, by the place of the ashes: 17 And he shall cleave it with the wings thereof, but shall not divide it asunder: and the priest shall burn it upon the altar, upon the wood that is upon the fire: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto the LORD.
[AD 1781] Richard Challoner on Leviticus 1:1
This Book is called LEVITICUS, because it treats of the Offices, Ministries, Rites and Ceremonies of the Priests and Levites. The Hebrews call it VAICRA, from the word with which it begins.
[AD 1781] Richard Challoner on Leviticus 1:3
A holocaust: That is, a whole burnt offering (olokauston), so called, because the whole victim was consumed with fire; and given in such manner to God as wholly to evaporate, as it were, for his honour and glory; without having any part of it reserved for the use of man. The other sacrifices in the Old Testament were either offerings for sin, or peace offerings: and these latter again were either offered in thanksgiving for blessings received; or by way of prayer for new favours or graces. So that sacrifices were then offered to God for four different ends or intentions, answerable to the different obligations which man has to God: 1. By way of adoration, homage, praise, and glory due to his divine majesty. 2. By way of thanksgiving for all benefits received from him. 3. By way of confessing and craving pardon for sins. 4. By way of prayer and petition for grace and relief in all necessities. In the New Law we have but one sacrifice, viz., that of the body and blood of Christ: but this one sacrifice of the New Testament perfectly answers all these four ends; and both priest and people, as often as it is celebrated, ought to join in offering it up for these four ends.

[AD 391] Pacian of Barcelona on Leviticus 1:6
We strip off the skin of a victim when we remove the illusion of virtue from the eyes of our mind. We cut its limbs into pieces when we carefully distinguish the content of a virtue and ponder it step by step. We should take care, so that when we conquer evil we do not replace it with frivolous goods. Otherwise those goods might produce inconstancy; they might lay hold of frivolity; they might wander off on the path of error; they might be broken by laziness and lose the value of work already done. In all things the mind should look around carefully and persevere in its provident concern. We should also note that we are sometimes afflicted by an impulse to illicit thoughts, because we are engaged in some earthly business, even if it is legitimate. When an earthly act is tinged with desire, even in a small way, the power of the ancient enemy grows against us and our minds are corrupted by no small oppression of temptation. Hence the priest of the law is bidden to burn in fire part of the victim that has been cut into pieces, namely, the head and the parts around the liver; but the feet and the intestines of the victim he must first wash in water. We burn the head and what is near the liver when, in the senses that rule the whole body and in our hidden desires, we burn with the flame of divine love. And the priest is commanded to wash the victim’s feet and intestines. Feet touch the earth, and intestines carry excrement. We are often set on fire with longing for eternity and in our sense of devotion long for our mortification. But since we still do something earthly because of our weakness, we tolerate in our hearts some illicit thoughts that we have suppressed. And when unclean temptation fouls our thoughts, what do they contain except excrement from the victim’s intestines? To burn them, they should be washed, for it is necessary that weeping in fear should wash away unclean thoughts. The heavenly fire can burn them in an acceptable sacrifice. Whatever the mind suffers in unfamiliar struggle or in the memory of its first conversion is to be washed, so that it can burn more sweetly in the sight of the one who beholds it.

[AD 735] Bede on Leviticus 1:14
In very many ceremonies of the law one who needed to be cleansed was ordered to be cleansed by [offering] these [birds]. A pigeon indicates simplicity and a turtledove indicates chastity, for a pigeon is a lover of simplicity and a turtledove is a lover of chastity—so that if by chance one loses its mate it will not subsequently seek another.
